Background: The aim of this study was to compare the concentration and immunoelectrophoretic characterization of alpha-1-antitrypsin (AAT) excreted in random fecal samples in children with acute and chronic diarrhea and in control groups.
Methods: Thirty-two children with diarrhea and 23 healthy children were evaluated. The concentration and characterization of AAT were determined by radial immunodiffusion and crossed immunoelectrophoresis, respectively.
